Answer:
The best adaptation to "I have been so affrighted" is letter D) I have been scared.
Step-by-step explanation:
As a verb, "affright" is synonym to "frighten". For example, "Ghosts won't affright me" means the same as "Ghosts won't frighten me." It can also be used as a noun, referring to a source of terror, the act of being scared, or a sudden fright. In the excerpt from Hamlet, "affright" is employed in its past participle form, "affrighted", meaning scared, terrified, frightened. Thus, the best option to adapt the sentence "I have been so affrighted" is letter D) I have been scared.
